Have you looked at http://sagemath.org/doc/reference/lfunctions/index.html ? What did you try?Sat, 11 Apr 2015 18:03:55 +0200https://ask.sagemath.org/question/26488/how-would-you-go-about-computing-special-values-of-l-functions-attached-to-modular-form-twisted-by-a-dirichlet-character/?comment=26504#post-id-26504
